►The BMW S85 V10 is one of the gnarliest sounding engines to ever leave the M-Division. They took inspiration from BMW's then F1 team and put together an absolute screamer of a powerplant. With 500 horsepower on tap, the E60 M5 and E63/64 M6 were the kings of the performance luxury sedan and coupes. However, the S85 has a chronic issue that isn't a quick fix. As with so many BMWs since the turn of the millennia, the S85 was built to be high revving and contained smaller bearings than might have been needed. Combined with a soft bearing material, the S85 has a penchant for destroying its rod bearings.
For the uninitiated, the rod bearings sit between the connecting rod and the crankshaft to provide a smooth and friction-free surface during operation. The connecting rods are bolted to a journal on the crankshaft. As the crankshaft rotates, so too does the journal inside the connecting rod. The bearing is there to interact with the oil and keep the crankshaft journal happy as it rotates inside the connecting rod. The original lead-based bearings were too susceptible to damage, as BMW later found out, and could wear out as early as 30,000-miles with a lead-footed driver. New Bi-Metal aluminum bearings were fitted to the engines in 2010 but by that time, five years' worth of models had already hit the roads.
To BMW's credit, they made the operating procedure of any S85 equipped very clear. The engine needed significant warm-up time before any sort of aggression could be applied, and a specific oil weight was required. Many owners ignored the warnings, but even those who did suffer from issues. Replacement is not a small job, as the entire bottom of the engine and many of the front ancillaries have to be removed. Just getting to the engine requires dropping the front subframe and all of the suspension attached to it. A dealership charges 55 hours to complete the job, and with the cost of parts, it can total well into the five-figure range.
Tackling the BMW S85 rod bearing replacement yourself is a very involved and critical job that can end with a destroyed engine if done wrong. However, with our kit and some instruction by Gareth, you'll have all the instructions and parts for the job. Our kit comes with every part you'd need to tackle the job yourself, including the updated Bi-metal bearings.

It’s great you guys provide these videos for the community. However the process shown here to clearance the Vanos pump back lash is incorrect. The dial indicator style and gauge set up is inadequate for this application. You need a lever type indicator. If you want to wing it with a plunger style that you’ve shown here you really should be coming at the gear teeth on an angle to get a decent reading of the gear lash. Setting up a plunger type indicator perpendicular to the gear (the method shown here) is wildly inaccurate. Couple that with the extremely tight tolerance bmw specs for this application and you asking for an issue down the road. We do a lot of these jobs and have seen many s85s come through the shop with noise and gear wear on the vanos pump drive system due to incorrect setup. Usually from a bearing job. This is tedious and complex work. A good shop will have invested in the proper knowledge and tooling to do this properly and it’s worth the cost of admission if being done properly. Cheers

Overall good information. One minor nitpick; the alignment tang on a bearing shell is that and only that - an alignment tang for ease of assembly. It has nothing to do with retaining the bearing while in use or keeping it from spinning. Each bearing half has slightly more than 180 degrees of arc length when installed in the cap or rod. The act of tightening the rod bolts "crushes" the bearings together and essentially makes them a press-fit in the big end bore of the rod. This interference fit is what keeps the bearing from spinning in normal operation.

Kudos to Gareth for tackling this project. What a nightmare of a job and total engineering failure on BMW. At least the current crop of BMW V8 S-engines don't have this issue. They just burn oil and leak coolant (ROFL). On an aside I need to stop watching these videos because it just depresses me that I can't DIY on my own BMW because I don't have a lift. It truly makes ones life so much easier.

The more of these videos that post, the more tow truck companies stay in business and the more jobs we will turn down. Because once it’s apart we won’t touch it. What happens to CarFax and service records? You have none. Amateur rod bearing replacement on an S85. The person that thought this was a good idea to post is an absolute idiot. You are placing consumers in a really bad situation when something goes wrong. If you can’t afford to pay a shop 15-25 hours for this job you shouldn’t be driving a BMW with an S85.
